...or, if your company has the budget, investigate Citrix Metaframe for UNIX operating systems.
You get far lower bandwidth usage, a more flexible front end - and up to 20 users can get a GUI connection to the Solaris server simultaneously out of the box. More connections can be added to this.
You can then have the CDE desktop on just about any device on the network, or you can publish individual applications rather than the entire desktop.
Also, you can also connect to this session remotely over a low bandwidth connection.
Good Luck!
